To all whom it may concern.-

Be it known that I, dorm A. STnANsKY,

a citizen of the United States, and resident,

of Pukwana, in the county of Brule and State of South Dakota, have invented certain. new and useful Improvements in Air- Mixing Devices, of which the following is a specification.

This invention relates tocharge forming devices for explosive engines and has more especial reference to,a novel air supply device therefor. r y

The dominant object of the invention is to provide a device adapted forarrange ment between the carburetor and intake manifold of an engine, whereby, a quantity. of. air will be automatically admitted to the explosive charge, thus, enriching the same and lending to the power thereof.

Anotherobject of the invention is to provide means for automatically admitting air in varying quantities, at predetermined periods, depending uponthe speed ofthe en- Utheri and further improvements and novel details in the construction and arrangement of the various parts of the device 'will be brought out more in detail in the description to follow, which, for a clear understanding of the invention should be considered in connection with the accompanying drawings forming a part heieof, and

- parts broken away and shown in section.

' Referring now more specifically to the drawings, and in connection wlth whlch like reference numerals will refer to correspond.

' ing parts throughout the several views, there is provided an apertured plate deslgnated 1,

the aperture in the said plate being of 'a size and shape complemental to the discharge end of the carbureter and the intakemani fold, while the plateis of a size and shape.

complemental to the flanged adjacent extremities or. the discharge portion of the carbureter and the intake manifold, whereby, the same may be securely fastened therebetween by passing belts or other suitable fagtening devices through the alined apertures 1n the flanged portions of the carbureter dlsoharge and intake manifold and similar openings 2 formed in the said plate. Ob-

viously, byso arranging the plate 1 between the carbureter and the intake manifold, the

' necessity of drilling or cutting the same is obviated A screen of fine mesh 3 is arranged over the aperture in the plate" 1 and serves as means for thoroughly vaporizing the explosive charge as delivered from the carbureter. A plurality of parallel ways 4 are formed in the intake 1 and communicate with the apertures therein, the lower portions of the said ways extending through externally screw threaded nipples 5 formed upon the said plate 1, whereby cylindrical valves cages 6, varying in size may be turned into engagement therewith. Intake openings 7 are formed within the bottoms of the cages and are normally closed through the medium of spherical valve members 8, which members are of different size and weight, as

shown in the Fig. 2. In this connection, it

is to be noted, that if desired, the ways. 4' extending through the plate 1 may be varied in size to accord with their respectivevalve cages 6, such as may dictate.

In operation, the engine'when running at low speed will create sufiicient suction in the intake manifold thereof to unseat the smaller of the spherical valves,.thus, admitconditions or preference ting a charge of air to the intake manifold and enriching the explosive charge being conveyed therethrough. However, should the speed of the engine be increased, the suction too would be increased, thus, unseat ing the larger of the spherical valves and permitting a greater quantity of air to be admitted to the intake manifold. llt is to be understood, that such suction as may be created during the initiative starting of the engine is not sufficient to unseat the spheri cal valves 8 and as a consequence, will not interfere with such operation.

Manifestly, the constructipn shown is capable-of considerable modification and such modification as is within the scope of my claims, I consider within the spirit of my invention. i,

I claim: p 1. In a device of the character described,

an apertured plate having a plurality of parallel ways varying in size formed therein and communicating with the aperture, screw threaded nipples formed upon the plate adscreen arranged over the aperture, a plujacent said ways, valve cages, varying in rality of screw threaded nipples formed size conn'ected, with said nipples, and spheriupon the bottom of the plate adjacent said cal valves varying in size arranged in the ways, valve cages turned into engagement 7 5 'cages and adapted to be operated. at predewith said nipples, and spherical valves ar- 15 termined periods. ranged in the cages varying in size and .1 2. In a device of the character described operable at predetermined intervals.

an apertured plate having a plurality 'oi In testimony whereof, I aifix my signature parallel ways varying insize formed therein hereto. 0 and communicating with the aperture, a JOHN A. STRANSKY.
